Silver Grade Basics
Understand grams per tonne, ounces per tonne and contained metal without treating grade as mine profitability.
What this topic covers
Understand grams per tonne, ounces per tonne and contained metal without treating grade as mine profitability.
Core mine-to-refinery ideas
Ore grade expresses silver concentration in a mass of rock or processed material.
Contained silver is calculated from tonnage and grade before considering recovery losses.
Profitability also depends on mining cost, recovery, byproduct credits, infrastructure, prices and many other factors.
Important tradeoffs
Mineralogy and associated metals determine which treatment route is appropriate.
Measurement and accounting
Contained metal, recovered metal and refined product are different accounting quantities.
Lifecycle perspective
This site ends at refined silver; downstream industrial applications are covered by the companion silver-use site.
